Minor identification and risk warning system in special scene based on probability confidence

This invention discloses a system for identifying and warning of minors in special scenarios based on probability confidence, relating to the field of data analysis. It includes: a data acquisition module, used to dynamically adjust parameters according to the ambient light at the entrance of the system-configured location and the shooting angle, to acquire facial and body feature image data of the object to be identified; and an extraction module, used to receive the image data acquired by the acquisition module, extract facial proportions, facial contours, body lines, facial skin texture, and body proportion information from the image data, and construct a feature vector set. This invention dynamically optimizes acquisition parameters based on ambient light and shooting angle to ensure image data quality, comprehensively extracts multi-dimensional key information such as facial proportions, facial contours, and body lines, and quantifies and constructs feature vectors. Through dynamic weight allocation, it strengthens the role of high-discrimination features, and combined with a probability model of minor characteristics, it achieves accurate matching calculations and outputs a reliable probability confidence value.

Body line correction and neural remodeling method and system based on eeg signal closed-loop feedback

PendingCN122392812AHuman bodyFeature extraction
The application discloses a body line correction and nerve remodeling method and system based on electroencephalogram closed-loop feedback, which comprises the following steps: collecting three-dimensional space posture data of a human body in a static or dynamic state, and calculating a force line offset between a current body line and an ideal force line model, so as to adjust the current force line to a target force line state corresponding to the ideal force line model; collecting a brain cortex electric activity signal of a user, obtaining electroencephalogram data, performing feature extraction, obtaining a quantitative index representing a neural coding intensity of the user to the current force line state, mapping the quantitative index into a multi-modal feedback signal, and adjusting a mechanical guiding strategy of a flexible actuator array until the user's brain establishes a stable neural representation of the target force line. According to the technical scheme, multi-modal feedback is used to enhance the somatosensory cognition of the user, the actuator strategy is dynamically adjusted, the brain forms a stable neural representation of the correct force line, and the user can still independently maintain a good body state after leaving the device.
